Thanks for sharing that, maybe it is somehow immune system responding/defending itself. As always it's good that it ended well without serious consequences.
Please share more, what was the batch number of your stuff? What did HL say when/if you reported the problem?
And let's wait and see for others to report. This must be more widespread problem than just us 5 guys.
Also HL saying nothing changed in the manufacturing is nothing more than hiding the problems from us.
Besides people say this source is not relevant, well, it happens from time to time again. Just go ahead and read Majestic lab thread. I was the one who exposed their quality issues and then some problems followed and they ran away. This is nothing new people.
We must stay vigilant and protect each other, one of us might suffer horribly if we don't look each others back and please never say it won't happen to me, it can happen to everyone at anytime.
